Unbalanced operation of a three-phase distribution system could incur more power losses, compared with the balanced operation. So far, phase information users in low voltage areas is not recorded by utilities and unbalance degree very significant some systems. Given this background, letter presents an integrated method for solving related issues including user identification based on spectral clustering mitigation, Mixed Integer Linear Programming (MILP) model then formulated. Some actual...

The paper mainly focuses on the synchronization of multiple-weight Markovian switching complex networks under nonlinear coupling mode. Based finite-time stability theory, Itô’s lemma, and some inequality technologies, criterion network models in mode is obtained; at same time, unknown parameters are also identified by an effective controller. In addition, several corollaries given to illustrate general applicability control rules paper. Finally, two typical numerical simulations prove...

In this paper, two different nonlinear coupled Markovian switching delayed network models with multiple weights are established, and the effects of parameter model uncertainties external disturbances fully considered. Firstly, based on finite-time theory, several sufficient conditions for synchronization networks obtained. Secondly, under feedback controller adaptive laws, when is achieved in a finite time, uncertain parameters can also be identified as true values. Finally, representative...

In recent years, the combination of artificial intelligence and power systems has been increasing. However, collection image datasets equipment is limited by places environments, so number collected relatively small, which makes it unable to provide sufficient data support for specific applications. We propose use Generative Adversarial Networks generate images electrical from existing sparse datasets, thereby increasing size dataset. this paper, three generative adversarial networks with...
